Operating systems like Windows 7 come with many utilities that get installed in the systems based on this platform. One such utility is the Performance Counter that is there by default in computers loaded with Windows 7. This utility enhances the disk drive's transfer rate and thereby makes the system slow. One can disable this Performance Counter easily. This can be done simply by keying in specific commands in the command prompt. The user also has the flexibility to activate this utility again, and this can be done through another command.
